SPECIFICATION formingpart of Letters Patent No. 252,026, dated January 10, 1882.

Application filed May 27,1881. (No model.)

To all whom it may concern:

Beit known that we, JoHN FLEMING, HENRY J. FLEMING, and JAMES BROADBENT, joint inventors, of Grand Junction, in the county of Greene and State of Iowa, haveinvented an Improved Steam-Generator and Agricultural Boiler, of which the following is a specification, The object of our invention is to provide a steam-generator that is specially adapted for 1 0 cooking feed, and itcan also be advantageously used for driving machinery, warming buildings, 86C.

It consists in forming, arranging, and combining a furnace, a water-reservoir,two steam chambers, and a tank in such a manner that the steam will rise from a chamber at one end of the reservoir and ascend to envelop the bottom and sides of the tank in a second chamber, and, after condensing, descend on an inclined plane to the opposite end of the reservoir, as required, to economize time, labor, and fuel in cooking feed or the steam may be conducted from the second steam-chamber in tubes and utilized for various purposes outside of and away from the generator, all as hereinafter fully set forth.

Figure 1 of our accompanying drawings is a perspective view, and Fig. 2 a central section, of our steam-generator and feed-cooker. To-

. o gether they clearly illustrate the construction,

operation, and utility of our complete invention.

a to represent the walls of our combined water-reservoir and steam-chamber. They may be made of wood or plate metal.

b is a metal bottom, to which the walls a are tightly fixed in any suitable way as required to produce water-tight and steam-tight joints.

0 c is a furnace connectedwith the bottom I) of the combined reservoir and steam-chest in such a manner that the products of combustion will come in contact therewith as required to heat the water resting upon said metal bottom 1). The furnace and complete structure 5 may rest upon feet, as shown, and required to be portable, or upon a fixed base when so desired.

d is a line connected with the rearend of the furnace to create a draft andto carry off smoke and waste products of combustion.

f is a diaphragm fixed in an inclined position in the lower portion of the combined reservoir and steam-chest o b in such a manner that the water in the boiler and reservoir will come in contact with its front or lower end, and its 5 5 rear orelevated end will be some distance above the level of the water, as required, to produce a steam-chamber No. 1, as shown in Fig. 2.

A series of tubes are fixed to the elevated end of the diaphragm to connect the steam-chamher No. l with the steam-chamber N o. 2 on the upper side of the diaphragm.

hrepresents a water cock or gage on the outside of the front end of the combined water: reservoir and steam-chest, by means of which the quantity of water in the boiler and reservoir can always be determined and regulated as required to prevent it from overflowing through a transverse opening, 6, at the front and lower end of the diaphragm, and also as required to maintain the steam-chamber No.1 in the rear and upper portion of the boiler or water-reservoir clear of water.

k 70 represent a series of bars or rods fixed in or to the sides a of the combined reservoir and steam-chambers in such a manner that they will form a support for a tank and also aid in strengthening and holding together the walls a of the structure.

Z is a tank, preferably made of sheet metal. Its top conforms in size and shape with the topedge of the walls a of the case, to which it is connected by means of a flange, or in' any suitable way, so that it will be partially supported by'said walls a and in combination therewith form a second steam-chamber No.

2, by having its bottom smaller than its top, and its four sides inclined inward and away from the perpendicular walls a, as shown in Fig. 2, and as required to allow the steam generated in the chamber No. 1 to come into contact with the four sides of the tank, and also the bottom of the tank resting upon the bars k.

m represents a boiler-feeder through which water can be readily introduced to the water- 5 reservoir by allowing it to flow upon the inclined diaphragm f, and from thence through the opening t' at the lower end of said diaphra gm.

n represents a steam-port and safety-valve. 10o

our complete invention its practical operation is obvious, and theadvantageous results contemplated and thereby effected are clearly apparent.

We claim as our invention- 1. The combined water-reservoir and steamchainbers, composed of the Walls a, the bottom b, the tank I, the bars 70, and the inclined diaphragm f, having an opening, 2', at its lower end and steam'tubes at its upper end, substantially as shown and described, for the purposes specified. V

2. The improved steairigenerator and agricultural boiler, composed of the following elements, to wit: the walls a, the bottom plate, I), the furnace 0 d, the diaphragm f '6 g, the bars k, and the tank Z, substantially as shown and described, to be operated in the manner 0 set forth, for the purposes specified.
